Sure. I guessed UABC because that's usual Brazilian fw (possible I'm wrong?), 1121 is too high anyway, so you have to forget current thread and follow link to other root method

Would you help me there on the other thread - I feel like I just need a little push before starting doing the process since the instructions lack some basic information I am not able to find elsewhere. Thanks.

Hi, I use this root (ue37es6100p) method but recently I lost root. I still have restoresmg widget and if I run it shows All green/ok and I also checked firmware version and is still the same. What could be happened?

You lost SamyGO after SmartHub update..
Block on your router
oempprd.samsungcloudsolution.com
apps-pub.samsungcloudcdn.comwww.samsungrm.net (for blocking remote management from Samsung)
to prevent SmartHub updating.
To restore SamyGO press RED instead of ENTER during widget installation. If this does not help then reinstall SamyGO (press ENTER during widget installation)
